Description

Novel mask structure
Technical Field
The present invention relates to a mask structure, and more particularly to a novel mask structure for reducing pressure difference when airflow passes through the mask.
Background
In order to meet the requirement of improving the filtering efficiency of the existing mask, a filtering layer with small pores is used as a material for filtering the mask, and when a wearer inhales, the filtering layer with small pores can intercept micro-particles in airflow, so that a better mask filtering effect is achieved.
The height aboveAlthough the mask with better filtering efficiency can achieve better filtering effect, the small pores for filtering the airflow can obstruct the airflow of the wearer either exhaling or inhaling, for example, when the mask uses a single PTFE (polytetrafluoroethylene) film as the filtering structure, the difference between the pressures of inhaling and exhaling is 35.7mmH respectively2O even 64.2mmH2O, such a large pressure difference may make the wearer feel difficulty in breathing, reducing the comfort of using the mask.
Disclosure of Invention
The problem that the wearer breathes difficultly is caused by large breathing pressure difference when the existing mask is used. Therefore, the invention is provided with the fiber structure layer on at least one of the front and back surfaces of the film filter layer, which can filter and slow down the air flow speed, reduce the pressure difference of the air flow passing through the mask during breathing and improve the comfortable feeling of wearing the mask.
To achieve the above objects, the present invention provides a novel mask structure, comprising a mask body and two ear-hanging structures respectively formed on the left and right sides of the mask body, wherein:
the mask body is provided with a film filter layer, the fiber diameter of the film filter layer is between 50 and 800 nanometers, at least one surface of the front surface and the back surface of the film filter layer is provided with a fiber structure layer, and the fiber diameter of the fiber structure layer is between 0.5 and 8.0 micrometers.
Furthermore, the fiber structure layer is polypropylene melt-blown non-woven fabric.
Preferably, each fiber structure layer of the present invention is a polypropylene melt-blown nonwoven fabric, a polybutylene terephthalate melt-blown nonwoven fabric, an ultrafine fiber nonwoven fabric, or a polyamide melt-blown nonwoven fabric.
Preferably, the membrane filter layer of the present invention is a polytetrafluoroethylene membrane, a polyvinylidene chloride membrane, a polyethylene membrane, a polypropylene membrane, or an electrospun membrane.
When the mask is used in the preferred embodiment, a mask wearer wears the mask of the present invention to cover the mask body in front of the nose and mouth of the mask wearer, and then the air flow of the inhalation and exhalation of the mask wearer can pass through the mask body, and the fine particles in the air are filtered by the film filter layer and the fiber structure layer.
Compared with the prior art, the invention has the beneficial effects that:
when the air flow inhaled or exhaled by the user passes through the film filtering layer and the fiber structure layer, the micro-particles carried by the air flow are filtered by the fiber structure layer and are retained in the fiber structure layer, and the speed of the air flow can be reduced when the air flow passes through each fiber structure layer, so that the pressure difference of the air flow when the air flow passes through the film filtering layer can be reduced, the difficulty in breathing of a mask wearer is avoided, and the breathing comfort of the mask wearer when the mask wearer wears the mask provided by the invention is improved.

Detailed Description
So that the manner in which the above recited features of the present invention can be understood in detail, a more particular description of the invention, briefly summarized above, may be had by reference to embodiments, some of which are illustrated in the appended drawings.
Referring to fig. 1 and 2, the preferred embodiment of the present invention provides a novel mask structure, which comprises a mask body 10 and two ear hook structures 20 respectively formed on the left and right sides of the mask body 10, wherein:
the mask body 10 is provided with a film filter layer 11 (filtering layer), the film filter layer 11 can be made of polytetrafluoroethylene film, polyvinylidene chloride film, polyethylene film, polypropylene film, or electrostatic spinning film, for example, the film filter layer 11 of the preferred embodiment is made of polytetrafluoroethylene film, the fiber diameter of the polytetrafluoroethylene film is between 50-800 nm, a fiber structure layer 12 (fibrilsayer) is respectively arranged in front of and behind the film filter layer 11, each fiber structure layer 12 can be made of polypropylene melt-blown non-woven fabric, polybutylene terephthalate melt-blown non-woven fabric, ultrafine fiber non-woven fabric, or polyamide melt-blown non-woven fabric, for example, each fiber structure layer 12 is made of polypropylene melt-blown non-woven fabric of 15gsm (grams per square meter), and the fiber diameter of each polypropylene melt-blown non-woven fabric is between 0.5-3.0 micron, the fiber diameter of each fiber structure layer 12 is larger than that of the membrane filtration layer 11.
The two ear-hooking structures 20 are ring-shaped pieces integrally extended from the left and right edges of the mask body 10.
When the invention is used, a mask wearer hooks the two ear hanging structures 20 of the invention on ears, so that the mask body 10 covers the front of the mouth and nose of the mask wearer, at this time, the air flow of inhalation and exhalation of the mask wearer passes through the mask body 10, as shown in figure 3, when a flow of inhaled or exhaled air passes through the membrane filtration layer 11 and the two fibrous structure layers 12, because the micro-particles carried by the air flow are filtered by each fiber structure layer 12 and retained therebetween, and the fiber diameter of each fiber structure layer 12 is larger than that of the membrane filter layer, the speed of the air flow of inspiration or expiration can be reduced when the air flow passes through each fiber structure layer 12, the pressure difference (pressure drop) of the air flow when the air flow passes through the membrane filter layer 11 is reduced, and the difficulty of expiration felt by a mask wearer is avoided.2O is reduced to 25.1mmH2O, and from 64.2mmH2O is reduced to 39.2mmH2O (at this time, the filtration efficiency of the mask is 98.67% and 99.78%, respectively, according to the test of CNS 14755Z 2125 standard, the test particle is 0.075 micron NaCl, and the test flow rate is 85.1Liter/min), and the breathing comfort of the mask wearer wearing the mask is improved due to the reduction of the pressure difference.
In addition to the above preferred embodiment, the fiber structure layer 12 is disposed on the front and back of the membrane filtration layer 11, or only on the membraneThe fiber structure layer 12 is arranged in front of the filter layer 11 or only behind the film filter layer 11, and the pressure difference between the inhalation and exhalation of the wearer is 20.9mmH2O and 54mmH2O (at the moment, the filtering efficiency of the mask is respectively 96.5 percent and 99.92 percent), and the effects of reducing the pressure difference during breathing and improving the comfort level of a mask wearer during breathing are also achieved. In addition to the above preferred embodiments, the fiber structure 12 of the present invention has a fiber diameter between 0.5 and 3.0 microns, and the fiber diameter of the fiber structure 12 can be changed to a size between 0.5 and 8.0 microns, and the fiber diameter of the fiber structure 12 is still larger than the diameter of the membrane filter layer 11, so as to reduce the pressure difference during breathing.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the scope of the present invention, which is claimed, and all other equivalent changes and modifications that do not depart from the spirit of the present invention are intended to be included within the scope of the present invention.
